Zeni sent me this really interesting, and amusing, hack of the Gakken SX-150 from the Maker Shed. Just remember to, drink, mod, and create music, responsibly!
I’ve made a modification to the Gakken Analog Synthesizer SX-150. The interface for making sound with the original SX-150 is with a small stylus. I’ve added another interface (there is a selector for switching between the two interfaces) so that it is possible to control the SX-150 through alcohol. There is a sensor that is attached to the SX-150 that is sensitive to alcohol. You can either put the sensor near a source of alcohol or if you just drank alcohol, you can just breath on it. The sound is altered depending on the alcohol level.
